A STUDY OF PAVEMENT SKID RESISTANCE AT HIGH SPEEDS AND AT LOCATIONS SHOWN TO BE FOCAL POINTS OF ACCIDENTS

The first phase of this investigation has been concerned with establishing a correlation between the skid resistance of a pavement's surface and the surface texture. The textures ranged from a very fine sand asphalt surface to a very coarse and highly skid resistant slag aggregate surface course. Cores were obtained at each of these locations and evaluated in the laboratory to determine the parameters of surface texture. A high degree of correlation was obtained when comparing the skid resistance values as determined from the surface texture with those obtained by field measurements of skid resistance. The second phase was concerned with high accident density locations. Over 450 accidents were used in the analysis of the skid resistance-accident correlation phase. Correlations were established for wet pavement accident percentages with friction coefficients measured at 40 mph and at higher speeds. (Modified author abstract)
